ALPHONSE GERBER, OF PATERSON, NEl/V JERSEY. RUBBING, BREAKING, ANDPOLISHING MACHINE FOR SILK OR SILK MIXED GOODS.

Specification of Letters Patent.

Patented April 24, 1 906.

Application filed liugust 8, 1904. Serial No. 219,875.

1'0 all, whom it may concern:

Be it known that I, ALrnoNsE GERBER, a citizen of the United States,residing at Paterson, in the county of Passaic and State of New Jersey,have invented certain new and useful Improvements in Rubbing, Breaking,and Polishing Machines for Silk or Silk Mixed Goods, of which thefollowing is a speciiication, reference being had therein to theaccompanying drawings.

My invention relates to improvements in rubbing, breaking, and polishingmachines for silk or silk mixed fabrics; and the objects of myimprovement are, first, to provide tension-bars rotating in the samedirection in which the fabric is passing and means for rapidly andeffectually regulating the tension of the fabric as desired; second, toprovide knife-carrying rollers that will by reason of the constructionand arrangement of the knives materially assist in rubbing, breaking,and polishing the fabric and removing imperfections, and, third, toprovide means operated from the main shaft of-the machine for spreadingthe fabric and removing imperfec tions therefrom while being driven at agreater speed than the fabric, but in the same direction.

A further object of my invention is to pro vide a new knife of apeculiar construction for such a machine as well as spreaders andpolishers that are not stationary nor driven and rotated by the frictionof the moving fabric, but which are rotated by other means.

From an economical point of view the object of my invention is toincrease production with a great saving in time and cost.

With these considerations in view the present invention aims to make apractical advance in the art to which the invention relates and has as achief concern better work, increased production, and reduced cost.

I attain these objects by the mechanism illustrated in the accompanyingdrawings, in which- Figure 1 is a vertical section or skeleton viewshowing the arrangement of the various rollers, spreaders, knives, andtension device, the mode of operating the same, and how the fabric ispassed through and among the said parts of the machine from the supplyto the take-up beam. Fig. 2 is an enlarged detail view of one of thecommanded or driven spreaders and polishers. Fi 3 is a detail view ofgaroller carrying'lafsetiof knives having a wavering, discontinuous, orbroken edge portion, Fig. 4, part of a straight-edge knife. Fig. 5 showsthe method of operating the tensionrollers; and Fig. 6 is a view of aportion of a knife with broken, wavering, or discontinuous edge.

Similar numerals refer to similar parts throughout the several views.

The numeral 1 indicates the framework of the machine, which carries themain drivingshaft 16, mounted in suitable bearings and having a pinion17 secured. thereto for driving the series of rotated bars and rollers.For the purpose of avoiding confusion intermediary gearing is omittedfrom the drawings; but the knife-carrying rollers 7 and 10 and thespreading and polishing rollers 5 5 are all driven in the same directionby the main driving-shaft through intermediary gearing. The roller 7carries four spirally-arranged dull-edged knives 8, eachhaving adiscontinuous edge, and the roller 10 has four straight dull-edged.knives 11, which are arranged spirally, but in an opposite direction,the arrangement being to the right on one roller and to the left on theother. 4

On the shafts 8 of the rollers 7 and 10 are swinging lever-arms 8 and onthe arms are the gears 8 In the outer end of one of said lever-arms isloosely mounted the rotatable tension-roller 6, and a similartensionroller 12 is located in like manner on the shaft of theknife-roller 10.

In Fig. 6, 8 represents the lowered portion or recess between thediscontinuous edge portions of the knife 8.

The fabric 3 is passed from the beam 2 to the take-up beam 13, passingunder the stationary rod 4, then cc between it and the roller 5, thenceover the tension-roller 6, down urder the rotatable rod 9, over thetor..- siolr-roller 12, under the other spreading and polishijrg roller5 and ontothe beam 13. Each of the rollers 5 5 is reversely threaded orprovided with four spiral threads, which are disposed in two differentdirections on the rollers, one-half their length to the right andone-half to the left, as shown i'nFig. 2. They have secured to theirextremities the gears 5 for driving purposes. The contact between thefabric and the knives of the rollers 7 and 10 and the tension of thefabric is regulated by means of the gear 14, which meshes with the gears8 and is turned by the lever 15 to operate the tension-rollers 6 and 12simultaneously. The lever 15 may be secured to any of the positions 18to maintain the desired tension.

The action of the rollers 6 and 12, which govern. the degree of tensionof the material, is not necessarily limited to the exteit of movementindicated by the dotted position shown in Fig. 1. Said rollers may bemoved farther toward the right or to the left In order that the materialmay be submitted to or freed from the action of the kjiiives to theextent desired. The same may be said with reference to Fig. 5, as thelever 15 may be moved to the right or left, according to the tension tobe given to the material and the extent to which the material is to beoperated upon by the k1 ives. Figs. 1 and 5 show how said results areaccomplished to a certain exteiit but I do not wish to limit the actionof the rollers 6 and 12 to the GXlJGIt shown. As the rollers 6 and 12are smooth a? d revolve in the arms 8*, they assist in the polishing ofthe fabric as well as regulate the tersio. thereof a; d the exte; t towhich it is subjected to the action of the kji'ives 8, having adiscoitizuous edge at" d the krives 11 havirg'a corti; uous edge. Thelcife-carryijng rollers 7 and 10 are adapted to be driven at triple thespeed of the moving fabric, but in the same direction, and the rollers 55 in the same direction, but at twice the speed of the rollers 7 and 10.

The spirally-arra1 ged k? ives havirj g a discortii uous edge arecalculated to grip the fabric more effectually than if they were allstraight continuous edges. They are arranged in a direction opposite tothe spirallyarranged k1; ives having co:.tinuous edges on the roller 10,and both series of kr ives thus cooperate to keep the fabric spread outand effectually break or take hardness or stiffness out of it. Thereversely-threaded rollers 5 serve to spread the fabric and the edges ofthe threads remove'knots, loose threads, and other imperfections fromthe surface of the fabric.

The invention may be utilized in rubbing, breaking, and polishing silkfabrics or mixed goods.

The machine shown is capable of modifications Without departing from thescope and spirit of my invention.

The main shaft may be driven in any suitable manner, and the take-upbeam and the other rotating members of the machine may be operativelyconnected with and driven by said main shaft.

With this description of my invention, what I claim, and desire tosecure by Letters Patent, is-

1. The combination with the rotary knifecarryi'ng members of gearsloosely mounted on each end of the shafts of said members, arms securedto each of said gears, tensionrolls mounted to turn by friction. in theouter ends of said arms, which project beyol'd the kIife-carryi; gmembers, an irtermediate gear meshin with the two gears which carry thetGllSlOfl-IOll arms, an operating arm or lever secured to said i:termediary gear and a guide for said operatii"g-arm provided with meat sfor holdirg said arm ii. the position desired, substaf .tially as setforth.

2. In a machire for fii'ishig' g silk or silkmiXed fabrics, a rotarymember, k1 ives havi; g a disco? tinuous edge spirally arranged on ajlidcarried by said member with the spirals turrii'g to the right, a secordrotary member, k; ives spirally formed thereon with the 'spirals turringto the left and having a contiruous edge, in combination with leverarmsloosely mou; ted on the er ds of the shafts of said rotary members,gears secured to the i?" 1161' ends of said arms, tension-rolls mou: tedthe outer erds of said arms and adapted to be turr ed by the friction ofthe moving fabric, an irtermediary gear meshing with above-mentionedgears, an operating lever-arm secured to the i3: termediary gear, and aguide for said operating lever-arm provided with meal s for holding saidarm in the position desired, for the purposes specified andsubstaiitially as set forth.
